Did you see the Vita launch and how slowly features were rolled out, with no explanation as to why or when they would be available? I think it is fair to take Sonys promises with a grain of salt until you see proof. I say this as someone who will buy the PS4, but all it takes is looking at Sonys history to see that they tend to promise more than they deliver

Yeah, I'm not saying the things they have promised won't happen, but I wouldn't count on all of it happening in time for launch day. Then again, some of these ideas might end up never coming to fruition like the ability of the ps3 to output to multiple screens. I hope they keep the features they have outlined but it is really to early to speculate either way.

The article was really pointless. It's basically summed up with the following words;

Sony promises things, and sometimes they don't deliver. Can they deliver this time around?

It also seems as if they've managed to forget the meeting wasn't a meeting of complete reveal. It's to send Microsoft on the defensive, and get people hyped. Yet another article that's purely for views instead of one that offers insight/expansion of what we already know. Really a shocker because Polygon usually has some top notch content, but I'm disappointed with this article.

The problem here is it's a bit more than that in this case. For example, the "PS3" touted at the PS3 reveal was much different than the PS3 that released. That's not hyperbole at all, and demoing a different product than the one you intend to sell is the same practice that caused Aliens: Colonial Marines to go up in flames lately. I would expect a service here or there to be down on launch, but pulling something like that is ridiculous.

The company talked about a online store powered by artificial intelligence that could help determine the games you might want to buy and then pre-load them onto your console for you. But it didn't offer details about how that would work.

Netflix, Amazon, and countless others have the ability to suggest things to you. Games have developers, publishers, genres, and sometimes sequels. Wouldn't be too hard.

If I can buy stuff from my smart phone and have it start downloading to my PS4 I don't see it automatically downloading stuff for you being a problem either.

It said games would be playable before they finished downloading, but later said that it wouldn't require third-party developers to deliver on that promise.

If you have an open world game, of course it will be hard to deliver that promise. It will work fine for more linear games I imagine.

Sony said it hopes to make PlayStation 4 games, or some version of them, playable on the PlayStation Vita.

And they showed it with Knack? He doesn't explain his problem here. For me personally the only downside will be R2/L2/R3/L3 most likely being the back touchpad.

They talked about wanting some form of interaction between tablets and smartphones and the new console, but not what that would be exactly.

If you're looking for an example, I can use my ipod to control the youtube app on my PS3.

The company sketched out the concept of using both real names and screen names when using its PlayStation Network. But it hasn't talked about the very real concerns surrounding real ID.

True.

It said every significant third-party game maker was making content for the PS4, though only two took to the stage during the event.

The event was over 2 hours. Wait until E3.

The company said it hopes to create a service that will allow gamers to stream PlayStation, PS2 and PS3 games to the PS4, but didn't promise it would happen.

True, but it's also not worth joining with Gaikai or even mentioning the possibility if the chances are slim.

Whether used games will play on the PS4, a point of contention and concern among many gamers, seems still unclear, with the head of its game studios saying that his "expectation" was that they would be playable.

Blocking used games will be up to the publishers.

Most noticeably, Sony's PS4 unveiling never featured the actual console, due to launch this holiday. The console is just a box, a Sony exec later told me, what really matters is what's inside it. But the thing is, we're not sure about that either.

Admittedly I don't know what all is supposed to be inside consoles, but don't we know this already? Or at least a good chunk? Or is he referring to the "subject to change" part? Like I said, odds are I'm missing whatever he's referring to since I don't know much about computer hardware.

In theory, the streaming while downloading is doable without 3rd parties provided the player is starting a new game. Before releasing, Sony's Gaikai system can launch the game and see what data files are accessed and in what order and prioritize the downloading of those files first. Anything that hasn't downloaded yet as the player plays get get queued up first and cause a bit of delays. The more people play, the more the system learns the priorities and organizes the download priority.

Put simply, while playing Mario Bros, the initial download is world 1-1, and while playing, 1-2, 4-1, & 1-3 are downloading in the background in that order, based on the history and learning algorithms of other players that streamed it. If you take the warp to 4-1, it might even push down the priority of 1-3 so it can bump 4-2, 8-1, and 8-2 to the top.

Lots of open worlds have the first few hours of gameplay in a limited area, so it wouldn't need all the data at once, and certainly wouldn't need all the cutscenes (and audio) of the bulk of the game right away either.

This is naturally a concern for many I'm sure, but if the specs are on par with what they showed at the conference I'll be getting a ps4. What I really want are new games with updated graphics, game engines, and gameplay. I'm confident that they will deliver that.

Why does the article only say 2 third parties took the stage? Just off the top of my head wasn't there Konami, Blizzard, Ubisoft, Activision, and square Enix. That's 5, I know there was also that indie game shown too which I didn't think was owned by Sony.
